Question: What effect does the presence of vault marking or side writing on a game-used bat have?

Answer: Vault marking or side writing provides evidence that a player returned that bat to the factory. These bats were marked this way by a representative at the factory, noting the return. In the case of side writing, the player's name, team, date and specs of the bat are often included in the grease pencil notations along the barrel. In some cases, the bat was retuned by another player, not the player whose name appears burned into the barrel. This could be a result of player trying out a teammate's bat and wanting to order a bat to the exact same specifications. In addition, the existence of side writing or vault marking does not, by itself, necessarily prove that a player used the bat -- although, most of the time, the two coincide. Often times, the existence of these special markings provides support as long as the bat also exhibits player use characteristics. It does provide proof that the player returned the bat for more to be manufactured.
